It has black flight membranes and its fur is a consistent shade of red over its entire body.[4] Two individuals captured in Honduras had forearm lengths of 50–51 mm (2.0–2.0 in) and body weights of 16–17 g (0.56–0.60 oz). Its ear length is approximately 18 mm (0.71 in).[5] Its wingspan is approximately 390.3 mm (15.37 in).[6]
The big red bat is found in Central and South America. Its range includes Panama, Brazil, French Guiana,[1] and Suriname.[6] In 1998, the species was documented in Honduras for the first time. This marked a 1,200 km (750 mi) extension of the species' range from the previously known northern limit.[5]
This species is infrequently encountered. The capture of two individuals in Honduras in 1998 marked the fifth and sixth individuals ever documented.[5] Due to the lack of information on its ecology, geographic extent, population size, and threats it faces, the IUCN lists this species as data deficient as of 2016.[1]
